servermgrd error – connections get SBBOD!

Hello, I hope someone can shed some light on this for me because I'm at a loss on how to resolve this. For the last couple of days, once or twice a day my G5 Xserve encounters this servermgrd error and all of my connected users get the Spinning Beach Ball Of Death for 5 to 10 minutes: [b]Dec 5 10:28:38 xservefs servermgrd: [28830] error in getAndLockContext: flock(servermgr_netboot) FATAL time out Dec 5 10:28:38 xservefs servermgrd: [28830] process will force-quit to avoid deadlock Dec 5 10:28:38 xservefs launchd: com.apple.servermgrd: exited with exit code: 1 Dec 5 10:28:38 xservefs launchd: com.apple.servermgrd: 9 more failures without living at least 60 seconds will cause job removal Dec 5 10:30:41 xservefs servermgrd: servermgr_dns: hostname and DNS entries for this server are synchronized Dec 5 10:30:45 xservefs servermgrd: TIME-CHECK: NSLXStandardRegisterService took 125.894081 seconds!n[/b] A few of my mobile users have also lost their dock and side-bar configurations as well. Does anyone know what causes this and how to resolve it? This is new to me. Best regards and thanks in advance to those of you who might have solutions for me. Bonthron
